ADDING MACHINE.

Application filed January 21, 1921.

My invention provides unimproved segregator, that is to say, a mechanismfor permuting each item that is set up thereon in its ordinaryBookkeeping terms (decimal terms, say) into terms of ordinary currencycomponents (including half-dollars, quarters and nickels, for instance),and registering accumuiatively the results of such permutations. Theprincipal use of my machine lies in payroll-segregation, and by itsoperation to set up and register successively the payroll items itdetermines, and indicates accumulatively, the precise quantity ofcurrency-pieces of each denomination required to meet the pay-roll,paying every item exactly and with fewest coins or bills or both.

To work such a machine in conjunction with an adding machineadvantageously ahbreviates making ready the payroll and facilitatesproof of the segregation. wherefore my device may preferably :be builtasa separable attachment for an adding machine. the two mechanisms workingin common from one set of manipulative devices.

Among the objects of my invention are to provide a segregator operatablepermutatively as above described, from a keyboard having no zero-keys,to indicate fewest currency-pieces, and having other functionaladvantages, and also to secure compactness, ruggedness, manufacturingsimplicity and economy, infallibility, ease of operation andmaintenance, and general efiieiency and convenience, in such a machine;and further objects and advantages that I attain by the features ofconstruction and combinations of mechanisms constituting my inventionwill become apparent from the following description.

In general, it will be understood that inv making up a pay-roll upon thesegregator equipped machine herein shown, one sets up each item indecimal terms on the scgregator keyboard. thereby setting up also thesame item on the adding machine and after each set-up one rcciprocatcsthe adding machineoperating lever, which serves in like capacity for thesc-grcgator, thereby simultaneously causing the adding machine toperform its items-listing: and accumulation-registering functions andthe segrcgutor to permutc each item into its fewest currency componentsand to register the same accumulatively. Th us if the first item be$18.98, the adding machine re isters the amount in its bookkee m 01Serial No. 138,822.

decimal form and the scgregator, upon its several appropriate counters(of which there is one for ex ery currency denomination within the rangeof the machine) registers as follows:

Of course the fact that currency issues usually are notlimited to thesevalues in which men ctary amounts are expressed in bookkeeping is thereason-for-being of a segregator, and while I show and will describe amachine intended for United States currency it will be understood thatin its broader aspect my invention may be embodied in machines for othercoin-age.

The adding mach-210.

()f the commercial adding machine outlined in the drawing, it suliicesto summarize that A is its decimal keyboard with the sequentiallynumbered keys 1 to 9 of each order in a vertical column or bank, makingnine horizontal rows, these keys controlling the decimal set-up of itemsthat will he recorded by the printing sectors B on paper strip 13 andwill be accumulatively registered in counter-section C, actuation beingeffected as usual by the operating handle Fl and total printing beingcontrolled by key A: and further to say that any key, normally springelevated, may be latched in deprescd position by suitable mechanism G(well known and only schematically suggested in F ig. 2) until releasedby handle E at the end of its full reciprocation.

The general m'gam'zatz'onQ 'lhe segregator mechanism is mainly housed ina compact casing 1, the cover-part 1 of which is removable while itsbase 1" is demountably secured on the face of the adding machine frameas by the supporting cross-brackets 2 and retaining latch-devices 3 thatengage grooved studs 3'. Such c asing contains the selector section 4that overlies part of the adding-machine keyboard A and also a forwardlyprojecting countersection 5 aligning with the righthand portion of theselector-section. The segregator keys 6. in seven banks, have verticalstems 7 slotted for guidance on frame-carried strips 7 and extendingthrough the casing bottom so that their feet 8 rest on the correspondingmldiug-machine keys of seven orders under the pressure of lightsprings7" (Fig. .2) and will transmit each scgregator set-up to the addingmachine. Selective depression of the keys of the lowest four orderscontrol the segregator operation, while suitable actuating means such asthe lever 9 having conneclion. preferably detachable. with the addingmachine lever l) to be worked from the latter. imparts power to cited;the segregalor registration.

Commercially, I prefer to make a ten dollar hill the largestcurreucy-denomination employed (although it may be extended to hills ofhigher denomination if desired) and so in the counting section I providenine counters in arrangement as indicated in Fig. 1. that I willrespectively term and letter, pennies (P), nickels (N), dimes (D), quartors (Q), halves (H), ones (I) twos (II),

fives (V) and tens (X) counters; and fairthc'r, since a single payrollitem is not apt to amount to a hundred dollars the capacity of thisdevice for segregation purposes is limited to $99.99 and I thereforeemploy only the four rows of keys at the right. Fig. 1. indicated as U.C. (units of cents), 'l. (l. (tens of cents) U. 1).- (units of dollars)and T. D. (tens of dollars),- to affect the counters, the remainingthree rows of segregator keys being merely,- in effect,- convenientextensions to the adding machine keys, for use merely in proving resultsshown on the segregator Without removing the latter from the addingmachine.

Each counter is )awl-ted, and its feed pa \rl mechanism is worlced by anappropriate indexing bar of the set 10', 10, etc., extending rearwardlythrough the cmm'ter-section.and each at its rear end detachahly pivotedto a corresponding actuator bar, 11'. 11". etc., that runs rcarwardlythrouglr the selector section with suitable slidable mounting in thecross members 4 and 4" of the selectorse'etioh frame, hotton'i-fiangedrear crossmcmber 4 (Fig. 19) holding;' their rear ends down. Each ofthese slide-liar st-ri'ictures is pressed rearwar'zlly as by springs 1!)or 11 and all of said actuator-bars'at'their rear ends co-act with aswinging bail 12 crossing the back of the selective section 4, pivotedin side lates 4,4", and worked from the actuating ever 9.- Thus, if anysaid slide liar structures have key operation to be described) beenotherwise freed, it. follows that when the adding machine handle E isrocked forward and (through lever 9) the bail 1:2 is stifling hack,thefr'eed slidest-ructures will be spring-impelled iearwardly therebypreparing their associated I'eecl pawls to feed the respectivecounters,- while upon the return stroke of the handle E the bail 12forces said slide-bars back to normal position, accordantly advancingthe appropriate counters.

The selector secfiou.

For each sliding actuator bar in the selector-section there is alatclrlinger 1.3 or 13 normally engaging a shoulder or notch 14 in theupper edge of the bar. each such linger being carried by a rockingshutter pivoted in the selector frame-nieuihers 4 and 4 above theactlmtor-bars and paralleling its controlling key-stem bank so that eachshutter may be gm'erned by one or more key-stems and when rocked therebymay unlatch one or more actuator-bars. There are only seven of theseshutters, numbered sequentially from 15 to 21 in the drawings, for thenine actuator bars, in the preferred embodiment of my invention, for thereason thatin certain instances two actuator bars may he alwaysunlatched together without detriment, and may be served by a. single twopronged latch linger 13 in for n .m'-intcrfcrcnce in the. confinedspaces be- I tween the key-stems. Each swinging shutter,

nm'nmlly held by a spring 15 with its finger in latched position,co-operates with the stems 7 of an appropriate key bank, its edgebottoming in notches 22 or 22' in said stems. If the key-stem is onethat, when depressed, is to move the. shutter to unla-tch anactlmtor-bar its notch 22 is short and cam-shouldered atits upper end;if the key-stem is not to move the shut-tert-he notch 22 is long forlost-motion. Keys U. C- govern, on the right, the shutter 21 for thepennies bar; on the left, the shutter 20 for the nickel bar 11": keys'1. C. control, on the right, the shutter 19 having the twopronge dfinger 13' for the dimes bar 11 and quarters bar 11" (also they controlthe nickel bar through tandem shutter :23 to be described) and on theleft the shutter 18 for the halves bar 11'': keys U. D. controLontheright the shutter 17 with its two pronged finger for ones and twosbars 11 and 11: and on the left, the shutter 16 for the fives bar 11':and keys 'l'. D. control only the shutter 15 for tens bar 11*.

Depremion of any key will cause one or more of the shutters to unlatchan actuator bar or bars, and in some instances this is all that. isneeded to free an actuator bar for the subsequent:- bail-controlledreciprocation that heretofore has been referred to. So it is of bars 11'and ll specifically, because a $5.00 hill is used invariably, and only,when a U. D. key from 5 to 9 inclusive is depressed and :1 50? piece iscorrespondingly usedinraria'uly and only. when a T. C.'key' numbered 5to 9 is depressed.- Furt-hermore neither of these currency pieces (amongothers) is used more than once in any item, so each such actuator bar11". 11, 11*,- 11 and 11 (F i5.- 5) that has no multi-step operation,-may have a stop shoulder s to strike supporting plate 4, while eachmulti-step bar may have asimilar shoulder to limit its range of motionto the maximum ever required of it. iVith respect to the two actuatorbars aforementioned then, the constructions are identical, the key-stemsU. D. and T. C. respectively cont-rolling them :z ipropriately havinglong or idle notches 22, at the left of key stems 1 to 4 and short orcam notches 22- at the left of keys 5 to 9 so that only thelast-mentioned keys trip out the respective latch shutters (see Figs. 7and 8). Thus it $5.00 be set up on the segregat-or, only the 5-key ofthe U. D. bank is depressed, only shutter 16 is operated to releaseactuator bar 11 and the reciprocation of the operating handle thereuponmay cause the $5.00 counter V to advance one number by this simple anddirect operation.

Where it is necessary thatone of the actuator bars be releasable by keysof two dill'erent' ordcrs, (as for example the nickel-bar ll that shouldbe releasable by certain keys of both the U. C. and T. C. banks) thismay be done as shown in Figs. 4, and 11 by making the latch-shutter 20directly operatable by the key stems of one (the U. C.) order andproviding a tandem release-shutter 23, extending lengthwise below theactuator bars and opera table by notches 22 in the key stems of theother (T. C.) order, this tandem shutter having its finger 23' hearingagainst the finger 13 of said shutter 20 as shown in Fig. 0. Suchprovision is necessary, to generalize, because the depression of any keyof the seg regator should cause the shutter-unlatching of all actuatorbars that must be called into service to register the value representedby the depressed key alone, and certain tens of cents keys called for anickel and a quarter.

Further, some actuator bars (for counters P., D., II and X) must have amulti-step range of movement variably dependent on what key of thecontrolling order is depressed, and for this control appropriatekeystems of banks U. D., U. C. and T. D. have stop-lugs 24extending'over the actuator bars, to co-operate with respectivelystepped or graduated-length notches 25 in the tops of the bars oppositethe respective key-stems. Keys T, C. control the bar 11 in aspecifically different way.

For two actuator bars this range-varying control only is needed,in-addition to shutterunlatching, namely for bars 11 and 11, becauseneither combinations nor permutations occur in the values that theyrepresent that is to say for amounts ending in 1 to 4 and 6 to 9 in thecents column, the pennycounter P must invariably work one, two, three orfour steps, and for amounts beginning with tens of dollars the steps ofthe counter X must always accord with the number of the key depressed.Thus, referring to Figs. 5 and 9 as illustratingthe selective controlover the $10.00 actuator, 11", every key stem T. D. has a. shortshutter-notch 2:2 to cause shutter to release the bar, as upon theillustrated depression of key No. 1, and each key up to No. 7 has ashort stop-lug 24 to cooperate ;with the adjacent one of the multistepnotches 25. Simply as a mechanical expedient. because an eight orninestep notch would he toolong, the bar has a finger 26 that, when keyNo. 8 is depressed, will strike the side thereof, giving an eight-stepstop. but when key 9 is depressed this finger will slide through theclearance notch 26 of key 8 until limitation-stop :s strikes the frontplate 4.

Similarly, referring to Figs. 5 and 6 as to the U. C. keys, the stem forthe 5-key has on its right side a long or idle notch 22 (pennies neverentering into an amount ending in five cents). but all other stems haveat the right short cam notches 22 for said shutter 21. The l, 2 and 3 kc's have stop lugs 2% [or co-operation with. one-, twoand three-stepnotches 25, and this arrangement is duplicated with respect to the 6, 7,and 8 keys. The 4 and 9 keys need no stop lugs as they permit the bar togo until its four-step limitation stop 3'' strikes the part 4. On theleft side of the stems the keys 5 to 9 have short camnotches 22 to rockthe latch-shutter for the actuating bar l1 of the nickel counter; keys 1to 4 having long, idle notches 22'.

lVit-h respect to the $1.00 and $2.00 actuator bars, 11 and 11.combination is necessary, that is to say, in order to make up successivevalues up to $4.00 one uses successively one $1.00 bill; one $2.00 bill,one $1.00 and one $2.00 bills; and two $2.00 bills; and from 6 to 9these combinations repeat (plus a $5.00 bill) lVith Figs. 5 and 8 (thelatter showing the 8-key depressed) it. will be seen that for suchcombinations all U. D- keys except the 5-key have cam notches 22co-acting with shutter 17 for the two pronged release linger 13 for bars11 and 11, and that the keys severally have appropriate short or longstop lugs 24 or 24, cooperating with the stopnotches of the actuatorbars. In bar 11 there are merely relocking-notches or slits for the longlugs but in bar 11 there are relecking slits and one-step notches forthe short lugs and one-step and two-step notches for the long lugs, sogiving the above-stated combinations. Specifically keys 2, 4, 7 and 9have the long lugs 2%, keys 1, 3, 6 and 8 the short. lugs and in bar 11there is a. relocking slit at keys 1 and 6, one-step notches atkeys 2,3, and 8, and two-step notches at keys 4 and 9. Thus if the 8 key bedepressed as shown, in addition to the key releasing the $5.00 actuatorbar 11 by the short notch 22 at the left as heretofore described, finger13 of shutter 17 releases bars 11 and 11", the former to make its singlestep movement limited by stop shoulder s and the latter to make amovement limited to a single step by the engagement of shortlu-g 24 inthe one-step notch The control of the actuator bars for quarters, dimesand nitkels, to register any amount set up in terms of fewest coins,involves pernmtation, or exchange of the two release selectionsappropriate to two keys of differentorders individually for a differentselection appropriate to the two keys jointly. Thus. the registrationappropriate to the depression of a 'l'. C. key alone may be variedaccording to the value of the U. C. key thatmay be concurrentlydepressed. For example, where :1 20 set-up requires registration of twodimes, a 25 set-up requires registration of one quarter; 40 requiresregistration of a quarter, one dime and a nickel, while requiresregistration of a quarter and two dimes; etc.

To secure the permutation the affected actuator bars 11", ll and 11,unlatchablc by the sh utters 20, 23 and 19 are stop-controlled fromcertain key stems of the T. C. and U. C. banks jointly throughpermutation stops 30 which may, by taking different positions, disableor free different ones of the several actuator bars that they serve andwhich are then'iselres governed, as to the difierent selective positionsthat they take, from said keystems.

From the right-hand side of the stems of keys '1. C. (Fig. 7),controlling the shutter 19, the latch-finger 13 common to the quartersand dimes actuator-bars, 11 and 11, will be operated by shortcam-notches 22 upon the depression of any except the -key, which has along or idle right-hand notch 22 beitanse neither the quarter nor thedime ever enters into a transaction between fifty and sixty cent-s.While the quarters and dimes bars are always unlatched together, it.will become a parent that if either is not needed it is disabled by theproper mutation-stop 30. Further, the 3, 4, 8 ant 9 keys, only, of thekey bank TC have the additional cam notches 22", lower down,co-operating with li projections 23 on the tandem-releasesliuttcr 23(Fig. Thus, upon depression of ,one of these four keys, shntte-r for thenickel actuator-bar 11" isth rown to nnlatching position; because onlyfor the gnio unts 46. 80 and 90 will the sole .depressionof a T ,0. keyrequire the registration of a nickel, all other calls for nickelregistrefion'depending on the keys of the U. C. ban

The eight permutation stops 30, identical in constrnction, extend infront of the 1-to-4 and (5404) keys of 'UC and TC and have theiryoke-shaped pivoted on a. longitudinal, m ne-carried 31 and acted uponby coiled springs 32 to the stops. The 5 keys need no in .the TC hankthe 5,-key does not trip any actuator affected by permutation $fiQ,ps.Each ira-mutation stop 30 is normally held in raised or inactiveposition by a controlling pin 33 on the stem .of thelcorresponding T..C. key so that when a tens of .cents key' is depressed thecorresponding stop 30 is freed for spring-depression. These stops 30 areoperable through two active stages or levels of depression, movement tothe first stage occurring immediately upon depression of a. T. .C.

i key and looking any actuator bu not needed for prom-r segregation ofthe amount expremed on the T. C.l ey itself, and the movement to itssecond or lower stag emgeoutrolled from the U. C. key-bank to establishsuch setting as need he to segregate the amount expressed on the T..C.and U. l-teys together. Thus each stop 30 has a tail 34, that, whenthe-stop is at the first stage ,of depression, bears against apermutation-shutter 35 (as in Fig. 1-1) which is pivoted on the shaft313ml pressed inwardly by all ,of the springs 32, each of which iscoiled around shaft 31 and bears against its permutation stop and thecommon shutter 35. To position the pcrn'mtation stops againstdisplacement along their shaft 31 shutter 35 may have its upper edgenotched as at35 (Fig. 32) so as to engage a portion of the base of'eachstep without interfering with the rocking nun'en'ients of either part.For rocking the shutter 35 the U. C. key-stems 5 to 9 have shortor camnotches 36; keys 1 to 4 having long or idle notches 3.5 correspondinglpositioned in their stems. Thus, when any stop 30 has been lowered tofirst stage position by depression of its as ociated .l. (f. key,com-urrent depression of a U. C. key numbered from 5 to S) will swinghack the permutation shutter 35 and allow the selected stop 30 todescend to second or lowest stage position, these two positions beingrespectively illustrated in Figs. 11 and 12.

The travel-limiting stop notches 25, and locking-slots in the tops ofthe actuator 11, 1]. and 11. appropriately located for co-action withthe several permutation stops, are accordantly made of two-stage depth,the first or upp;-.-r-stage uoteh-forruntion heihg referred to as 25*and the second 'or lowerstage formation as 25". The necessanfpermutations sometimes require one of the actuator bars 11 tor 11" to helocked in the first stage and freed in the seqond stage; and in sat-hinstances the appropriate notches 25 for the second stage of these baniare raidercut. Such ,a condition never egzists as to the nickel bar 11"and therefore no second stage notches of this bar need he'nnder-cirtjAccordantly with these 'mnditiolis, each stop-member 30 provides in itsblade a solid harrier-portion to cooperat with the nickel-bar notchesand, force-operation with the notches of the dimes and quarters bars 11and 11", it has a narrow band or barrier 30* at its lower edge that willcooperate with the notch-formation 2,5? \yh enthe' permutation stop isin first stage position. and above the barrier 1 slot or c learancespace 30" to give passage for the actuator-bar port-ions of the firststage formations that over-hang those second stage notches 25 which areunder-cut.

The not-eh and-harrier arrangement ap ortenant to the l-key of the T.

For the 2-kev (which also unlatehes only thesetwo bars) the notchantLh-arrier arrangement gives in the upper stage are-locking o the" quarters liar and av two-step release of the dimesbar, while in the lower shige gires a release of the qua r-
